I used to have two dogs
Both rescues
We think one of them was abused by his previous owners
But anyways
Whenever we would come home
He would make this noise that sounded exactly like "hello"
It was so sweet
I had a dog who wasn't abused, but she was always tripped over (cuz her previous owners were older and couldn't always see their little dog) She was the best doggy, and very protective too... I miss her
